Nubank recently raised $400M at a $10B valuation and they depend on Datomic [1] heavily for their core systems [2]. The RDF database marketplace is very established [3], and the likes of MarkLogic, DB2, and Oracle have clearly encountered profitable reasons to add RDF support. I believe RDF has good traction in knowledge-intensive industry domains such as clinical research and life sciences. Disclosure: I work on Crux [4] which adds bitemporal versioning and eviction to a document->triplestore model running on top of Kafka.
